PROUD MAMA: Lulu stood up for new mums that didn't bounce straight back to their pre-baby figures [WENN]

The CBB star recently stood up for Kerry Katona and all new mums that refuse to immediately diet and work out to fit back into their size 8 skinny jeans.

While assuring us all that springing back into shape days after popping out a sprog is pretty much impossible, Lulu also mentioned a certain heiress that had a washboard stomach just weeks after giving birth.

Luisa wrote: "Recently, Tamara Ecclestone – who has more prams than I’d like to shake a stick at and seemingly just pushes them round all day in different outfits posing for set-up pap pictures – recently hit back at Twitter trolls.

"The new mama said her trim figure was down to 'breast feeding and looking after her daughter'. *Cue eye roll* What a load of crap."

“I'm not sure how eating well and breast feeding is a bad example”

However, while the opinionated businesswoman published this piece two weeks ago, Tamara only came across the criticisms today, and took to Twitter to voice her anger.

The 29-year-old socialite, who welcomed baby Sophia in March, tweeted: "Life according to @TheLuluLife! Apparently I have a PT and I am dieting thus setting a bad example for new mothers."

Bernie Ecclestone's daughter, who was back in her figure-hugging ensembles weeks after giving birth, continued: "Not that it's anyone's business however I haven't set foot in a gym once since having my baby nor am I dieting.

"I'm not sure how eating well and breast feeding is a bad example. I can think of far worse! Sad that ignorant people pass so much judgement."

But don't think our Lulu was about to take this criticism lying down.

The feisty star wrote back: "Dnt think its bad example think it's bad when you dnt admit it & u give ppl the wrong idea about why u have ur bod back quick."

Luisa also added that she wasn't judging Tamara, saying: "I have a nanny, PT & full time job think celebs should be honest with the public re body image that's all."

Miss Zissman elaborated on her criticism of Tamara's post-baby body in an interview with new! magazine.

The new BBBots regular said: "She should admit she has help. It’s not bad to lose the weight, it’s the image celebs portray that they’re like other new mothers. They have nannies, so they can leave their babies and exercise for hours every day. And they have help so they can basically starve themselves thin. New mums can’t do that – they need to eat because they need the energy and the rest."

If this is the reaction Luisa sparks when she's not on TV, we can't wait to see the fallout from her BBBots appearances.
